Anthurium plant named &#39;ANTHDINWAQ&#39;

ABSTRACT

A new and distinct variety of  Anthurium  plant named ‘ANTHDINWAQ’ particularly characterized by having durable rounded pink spathes that retain their color for a very long period of time, dark green durable glossy leaves, rich and early flowering throughout the year, rich shoot formation, a very compact and full plant habit and a plant height of 18 cm to 22 cm, is disclosed.

GENUS AND SPECIES

Anthurium andreanum L.

VARIETY DENOMINATION

‘ANTHDINWAQ’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium,botanically known as Anthurium andreanum L., and hereinafter referred toby the variety name ‘ANTHDINWAQ’. The new variety originated from ahybridization made in October 2004 in Bleiswijk, The Netherlands. Thefemale parent is a purple-pink Anthurium pot plant named ‘ANTHUCOEN’(U.S. Plant Pat. No. 22,630) and the male parent is a pink Anthuriumplant named ‘ANTHBESKA’ (unpatented).

The new variety was selected in September 2006 from a selection of thehybridization and has been asexually reproduced repeatedly by tissueculture in Bleiswijk, The Netherlands over a five-year period. Thepresent invention has been found to retain its distinctivecharacteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in Europeon Nov. 19, 2012. ‘ANTHDINWAQ’ has not been made publicly available orsold anywhere in the world more than one year prior to the filing ofthis application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Bleiswijk, The Netherlands.

-   -   1) A bright glossy pink colored small sized spathe;    -   2) Purple spadix;    -   3) Glossy leaves; and    -   4) Very compact plant habit.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘ANTHDINWAQ’. The data which define thesecharacteristics were collected from asexual reproductions carried out inBleiswijk, The Netherlands. The plant history was taken on 48-week oldplants which were planted from tissue culture in 12-cm pots and grown ina greenhouse between 19° C. and 24° C. Observations were made inFebruary 2013. Color readings were taken under 5000 lux natural light inthe greenhouse. Color references are primarily to The R.H.S. ColourChart of The Royal Horticultural Society of London (R.H.S.) (2001).

After the spathe is fully            opened the peduncle elongates some extra centimeters.        -   Arrangement.—Spathe angle with the peduncle is between 90            degrees and 110 degrees; the spathe stands on a wiry            peduncle about 3 cm to 6 cm above the foliage.        -   Shape.—Rounded with a flat (non blistered) surface.        -   Apex.—Acute.        -   Base.—Obtuse.        -   Texture.—Shiny, non blistered (both sides).        -   Margin.—Entire.        -   Size.—Height: 11.0 cm to 16.0 cm (Peduncle length at            maturity) Length: 4.0 cm to 6.0 cm Width: 6.0 cm.        -   Color.—Just fully open: Upper surface: RHS 51A Lower            surface: RHS 51B 7 to 8 weeks after opening: RHS 51A 14 to            16 weeks after opening: The primary colour is between RHS 51            B and RHS51C, depending on cultural conditions. The lobes            accumulate very slowly some chlorophyll. The lobes become            green (towards RHS 146A) very slowly.-   Peduncle:    -   -   Shape.—Erect.        -   Cross-section.—Round.        -   Length.—11.0 cm to 16.0 cm.        -   Diameter.—0.2 cm to 0.3 cm.        -   Color.—RHS 146B (Green) at the base and just below the            spathe some anthocyanins are present and colour is            approximately RHS 182A.-   Flowering time:    -   -   General.—One small rooted untreated tissue culture plant of            2 cm tall will flower, after 4 to 6 months 2 or 3 blossoms            will appear, depending on the season. More blossoms appear            after some additional weeks so that a full flowering and            commercial plant will have 6 to 10 pink spathes. Smaller            blossoms may occur on less mature growth.-   Spadix:    -   -   Size.—Length: 1.5 cm to 2.5 cm (depending on flower size)            Width (at apex): 0.3 cm to 0.5 cm Width (at base): 0.4 cm to            0.6 cm.        -   Shape.—Columnar.        -   Angle from spadixtip to peduncle.—180 degrees (spadix is in            one line with peduncle).        -   Texture.—When the spathe is unfurling the spadix is smooth.            When the spadix matures, very small stigmata protrude. The            stigmata are evenly distributed round the spadix. The spadix            matures from base to top, slowly giving the spadix a bit            rough appearance.        -   Color.—Immature: RHS 171A (Greyed-orange) to RHS 184C            (Greyed-purple) Mature: RHS 77B (Purple) Ages to: RHS 182B            (Brownish).-   Flowers:    -   -   Quantity per spadix.—70 to 120.        -   Spadix flower arrangement.—Bisexual, rounded in            cross-section.        -   Shape.—Rounded.        -   Size.—Length: 0.1 cm to 0.2 cm Diameter (maximum): 0.2 cm.        -   Color.—RHS 77B (Purple).-   Reproductive organs:    -   -   Stamens.—Not visible.        -   Pollen.—Very few or absent.        -   Pollen color.—Not measured.        -   Pistil.—Quantity: Many Length: Less than 0.01 cm Color: RHS            84C (Pale violet).        -   Style.—Not observed.        -   Stigma.—Shape: Ovoid Diameter: Less than 0.01 cm Color: RHS            77B (Purple).        -   Ovary.—Rarely visible.        -   Ovary color.—Not measured.-   Fruit and seed set: Seed production has not been observed to date.-   Disease and insect resistance: No particular resistance or    susceptibility that is different from other Anthurium varieties.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘ANTHDINWAQ’ differs from the female parent and commercial varietyAnthurium ‘ANTHUCOEN’ (U.S. Plant Pat. No. 22,630), in that ‘ANTHDINWAQ’has a pink spathe colour, whereas ‘ANTHUCOEN’ has a purple-pink spathecolour. Additionally, the spathes of ‘ANTHUCOEN’ are oblong, whereas thespathes of ‘ANTHDINWAQ’ are round.

‘ANTHDINWAQ’ differs from the male parent ‘ANTHBESKA’ (unpatented), byhaving a smaller spathe, leaves and overall plant habit.

‘ANTHDINWAQ’ can also be compared to commercial variety Anthurium‘ANTINKELES’ (U.S. Plant Pat. No. 12,115). Additional comparison data isshown in Table 1 below.
